AUTOMATICALLY-DU M PING BOAT.

SPECIFICATION formingpart of Letters Patent No. 226,960, dated April 27, 1880.

Application filed March 2, 1880.

To all whom it may concern;

Be it known that I, NATHAN BARNEY, of Bergen Point, in the county of Hudson and State of New Jersey, have in vented certain new and useful Improvements in Automatically- Dumping Boats; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others sk lled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The invention relates to an improved automatically-dumping boat and it consists in the construction and arrangement of parts, as will be hereinafter more fully set forth.

In the annexed drawings, Figure 1 is a plan view. Fig. 2 is' an end elevation with the bottom closed. Fig. 3 is a central vertical section with the bottom open, and Fig. 4 a similar view with the bottom closed.

In 'the drawings, A represents the platform or deck; B, the cross-pieces on the under side of the deck, to which the bottom is pivoted; O U, the divided bottom 5 D, the ends 5 E, cogs on the ends; F, sliding bolt; a, projections.

on bolt 5 b, rack on bolt 0, cars on end pieces to engage with projections a on bolt; d, rod; 0, pinions secured on rod (1 and engaging with the racks Z) f,- bearings for the rod d.

The platform A is constructed in the form shown, the cross-pieces B strengthening the same, and their ends passing in slotted standards secured upon the side of the bottom G 0 and pivoted thereto, as shown, thereby allowing the bottom to open and close as desired. The upper portions of the end pieces are provided with cogs E, which, when the bottom is opened and closed, engage with each other and guide the parts in the proper position.

The rod d may have attached to it a permanent lever, or it may be square at certain portions to receive a wrench. When the bottom (ModeL) tions at from under the ears 0 and permit the load to pass through. If the load is not perfectly dumped, the bottoni may be held open and the boat towed in that position until it is perfectly free from its load. As soon as the boat is relieved from the load, or, if held open by the bolt, as soon as the bolt is drawn the bottom closes automatically and is secured by the bolt, when it is ready to receive another load.

The advantages of this device are many. It greatly reduces the cost of labor, as one man can operate the device easily. Its simplicity and cheapness of construction are obvious, and it is not liable to get out of repair. The boat may be provided with a bow, if desired.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A dumping-boat having its bottom in two parts, pivoted on opposite sides of a suitable platform, and the ends provided with cogs, whereby the boat is opened longitudinally to dump the load, and is returned automatically and accurately to its former position, substantially as and for the purpose set forth.

2. The platform A, cross-pieces B, having the bottom 0 O pivoted thereto, and the end pieces, D, having the cogs E, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed mysignature in presence of two witnesses.
